6 FAQs about [Battery production What is aging]

What causes a battery to aging?

Batteries are electro-chemical devices with chemical reactions inside the battery that eventually cause material degradation, thus reducing a battery’s usable capacity. The rate of such reactions, or the rate of aging, depends on multiple factors, such as temperature, state of charge (SOC), and the number and depth of charge/discharge cycles.

What is the purpose of aging a battery?

The purpose of aging is to stabilize the battery’s electrochemical performance and make its voltage more accurate. Aging can be done at room temperature or at a higher temperature. The total formation and aging process time ranges from 3 days to 3 weeks. The cost and energy input for this stage of the cell manufacturing process is significant .

What factors affect EV battery aging?

The mileage of the EV’s daily use is related to the battery depth of discharge (DOD); driving speed and acceleration are related to the battery discharge current; and the main environmental factor that influences the battery aging is the temperature. These factors and the corresponding influences on the battery are summarized in Figure 10.

How does the state of charge affect battery aging?

The further the state of charge (SoC) is from this middle point, the faster the battery is aging, with all other parameters being equal. However, this process is highly non-linear, with real effects only notable at the very top and bottom of SOC range, accumulated over long time periods.

What are the challenges in battery formation & aging?

Several challenges exist when it comes to formation and aging. The first is that the process must be conducted on every cell that is made. The process must be precise so that the batteries are formed correctly and the process can change often as research and design teams improve methodologies.
